A heat pump that breaks down in Sterling County has almost certainly been carrying a light weather load, and a contractor diagnosing the failure works from that fact. 41 severe weather events were recorded in Sterling County, Texas between 2015 and 2024. At that rate, severe weather lands here now and then rather than grinding through the system season after season. Refrigerant seals wear, capacitors weaken, and compressors fatigue on their own schedule regardless of storms. A contractor quoting a repair will look at the age of the unit and how consistently it was serviced before attributing anything to conditions outside.
Half the homes in Sterling County, Texas were built in 1983 or earlier (2020-2024 ACS 5-year). That gap between when these houses were framed and when their current equipment was put in means the refrigerant lines, electrical connections, and internal components a contractor finds have already been adapted at least once. What matters when a repair opens a heat pump here is whether the parts it takes are still in production and what the opened system's coils and contacts actually show. A building that old has had time to host more than one system, and each changeover leaves behind its own wiring decisions and line-set choices for the next contractor to read.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad outside the house and holds the compressor and the condenser coil. The compressor is the heart of the system, and when a heat pump stops moving heat the way it should, that is where a contractor looks first. The condenser coil sits around the compressor, and a damaged or dirty coil can stop the whole unit from doing its job.
Inside the house, the air handler holds the evaporator coil and the blower fan, and it is responsible for moving conditioned air through the home. The refrigerant lines connect the two units, and the reversing valve inside the outdoor cabinet is the part that lets a heat pump both heat and cool. A failed reversing valve is a common reason a system blows warm air when it should blow cold, or cold when it should blow warm.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts apply and need attention in your specific home.

Severe Weather Events in Sterling County
Extreme weather puts real stress on heat pump systems, pushing them to run harder and longer than normal conditions demand. How often that happens here shapes how much wear a unit accumulates and what kind of repair work shows up over time.
